Why You Don’t Always See Megawatt-Hours (MWh) In Reporting

Measuring generation capacity of a solar or wind farm, for instance, is relatively simple — you can refer to its base figure or its peak figure (which is why you sometimes see MW or GW followed by a “p”). However, the same cannot be said for energy storage, as base capacity is, while a valuable figure, not the most valuable figure. Unsurprisingly, the figure people want to know for energy storage projects is how long it can provide power — which is where megawatt- or gigawatt-hours (MWh/GWh) come in; how many megawatt-hours can your new energy storage provide
